Usable Data Cost Calculator

Estimate the value of one purchase. Enter the period that purchase covers and how much daytime and night data you expect to use each day. Unmet demand stays visible: this tool does not buy extra bundles to fill the gap.

How the allowance arrives

The example is hypothetical, even if its inputs resemble a published offer. It assumes 30 days, 500MB anytime and 500MB night each day, R169 once, 250MB daytime usage daily and no night usage.

Rules and limits

For daily releases, usable data is calculated for one day, then multiplied by the number of days. For a pool, daily demand is multiplied by the period before applying the wallet limits. Night usage takes available night data first; remaining usage can use anytime data. Unused equals allocation minus used. Cost per GB used is the purchase price, rounded to cents, divided by used GB. The anytime-only figure assigns the entire price to anytime data and gives night data zero value.

This assumes identical usage every day, reliable service, no app-only restrictions, no additional purchase, no rollover and no existing balance. It is not an operator-specific depletion forecast. Amounts use 1GB = 1,000MB and are rounded to three decimal places. Use the exact validity period and night window; hourly, calendar-month and changing daily-use patterns require a different model.

Compare repeat purchases fulfilling the same demand, or check product expiry rules.
